    backward filtration is impossible in the subcutaneous connec- tive tissues of the limbs, in muscles, and in all glandular structures which have an analogous build to the submaxillary gland. Theoretically we may say that absorption by filtra- tion is possible only in those regions of the body where a sudden rise in tissue-pressure will not be propagated to the neighbourhood of the large veins. Such regions might be found in the cutis itself or in the intestinal villus, but such Southey tube 0. , . ,. T. Cannula to Manometer ' Injecting Southey tube C Fig. 8.—Diagram to show arrangement of experiment on absorption of fluid by tbe blood-vessels. By the injecting needle fluid was injected into the subcutaneous tissue, and the pressure of the oedema fluid thus produced was measured by means of manometers attached to the two Southey's tubes (small perforated silver tubes). The flow through the vein was measured by allowing the blood to drop from its proximal end on to a drop counter, while changes in the pressure peripheral to the oedema were determined by a manometer attached to a _L cannula inserted into a vein of the foot. minute spaces are not at present accessible to our experi- mental methods of investigation. So far as our results go, reabsorption by a process of back-filtration must be excluded. There is however another factor present which would aid absorption of fluid by the blood vessels, and might therefore account for the reabsorption of the tissue fluid which occurs after haemorrhage, or when the general blood pressure is lowered. In Lecture II. I called your attention to the fact that the non-diffusible constituents of the blood serum, chiefly
